So today was clean the yard day for my sister and me. I had to cut the grass while she trimmed the tree. It was really hot, but luckily there was a strong breeze. Strong enough to take the straw hat from my sisters head and send it flying down the street. She chased it down the street traveling about 40 meters. Although she traveled a total distance of 80 meters, her displacement measurement was zero. Distance is defined as total length of travel while displacement is defined as the change in position. From the hat back to our house, my sister traveled a total length of 80 meters. But from the hat back to the house, she traveled forward 40 meters then turned around and walked back 40 meters, causing her displacement to measure zero. This displayed an example of kinematics.
This once happened to me when I was cleaning the yard one day! Haha, what a coincidence. I like how you connected kinematics to this because it made it easier for me to understand what this unit was about.
ReplyDeleteI hate when it's windy and you have to chase after things that are flying away! But, I like the example that you used to relate to kinematics(:
